I accidentally wandered outside the map

I accidentally found a map exit and wandered outside the map. I decided to record it and do it again so you could see the video for yourselves in case this is something that needs patching (or it can just stay as a fun little thing, Idk).

When the character I played wandered outside the map, the remaining team members did not follow, it seems they are unable to follow outside. When I came back inside the character I was controlling was stuck behind some invisible wall not actually able to re-enter the map area. The fix to that was to switch to a different character, select to regroup and walk away from the stuck character. Once I got far enough away the stuck one teleported to the others and I was able to play as that character again.
